Description

Technical Field

[0001] This utility model relates to the field of cable laying and installation frame technology, and specifically discloses a cable laying and installation frame for communication engineering. Background Technology

[0002] Telecommunications engineering is the nervous system of modern information society, its foundation relying on ubiquitous wired communication networks. During the construction of these networks, cables (including fiber optic cables and coaxial cables) need to be reliably secured to supporting structures such as utility poles, walls, or cable trays. The core function of cable installation racks is to provide stable support and fixation for these cables, preventing excessive sagging, swaying, or wear due to their own weight, wind loads, ice loads, and other external forces, thereby ensuring stable transmission of communication signals and extending the service life of the cables.

[0003] In existing technologies, rigid clamps are typically used to secure cables, providing support and fixation. However, these devices have significant limitations: First, when multiple cables need to be fixed on a beam with varying outer diameters, different clamps must be matched to cables of different specifications, making the operation extremely cumbersome and inefficient. Second, if multiple cables are fixed at once using a single clamp structure, these cables must be of the same specification to achieve synchronous clamping and fixation through simultaneous movement of the clamps. This limits the device to fixing only cables of the same specification, lacking the necessary flexibility and adaptability in practical engineering applications.

[0004] Therefore, a cable laying and installation frame for communication engineering is needed to solve the above problems. Utility Model Content

[0005] This utility model proposes a cable erection and installation frame for communication engineering, which can press and fix cables of different diameters onto the support plate at one time without the need for special clamps for different specifications of cables. It is easy to operate and effectively solves the problem of poor flexibility.

[0006] This utility model is implemented as follows: a cable erection and installation frame for communication engineering includes a vertical plate. A support plate for bearing the weight of the cable is fixedly connected to the right end of the vertical plate. Both the front and rear sides of the support plate are bent downward to form a bending part. A fixing mechanism is provided on the support plate. The fixing mechanism is used to press and fix cables of different diameters onto the support plate.

[0007] The fixing mechanism includes a fixing plate fixedly connected between two bending parts, a lead screw rotatably connected between the two fixing plates, a movable plate threadedly connected to the outer wall of the lead screw, a drive plate fixedly connected to the upper end of the movable plate, a flexible belt fixedly connected to the right end of the drive plate, and a plurality of grooves with a triangular cross-section distributed horizontally on the upper end of the support plate. A first guide roller is rotatably connected inside each of the plurality of grooves, and the flexible belt passes around the plurality of first guide rollers and is fixedly connected to the upper end of the support plate.

[0008] The fixing mechanism also includes a manual drive mechanism for driving the lead screw to rotate.

[0009] As a preferred embodiment of the cable erection and installation frame for communication engineering of this utility model, the manual drive mechanism includes a drive frame fixedly connected to the right end of the right side fixing plate, a worm gear rotatably connected inside the drive frame, a worm wheel meshing with the outer wall of the worm gear, a transmission shaft fixedly connected between the worm wheel and the lead screw, and a handwheel fixedly connected to the lower end of the worm gear.

[0010] As a preferred embodiment of the cable erection and installation frame for communication engineering of this utility model, the right end of the support plate is provided with a through groove, and the inside of the through groove and between the two bends are respectively rotatably connected to the second guide rollers. The flexible belt passes through the through groove and around the two second guide rollers.

[0011] As a preferred embodiment of the cable erection and installation frame for communication engineering of this utility model, slide rails are installed on opposite sides of the two bending portions, and the moving plate is slidably connected to the two slide rails.

[0012] As a preferred embodiment of the cable erection and installation frame for communication engineering according to this utility model, the corners of the support plate and the two bends on opposite sides are all smoothly transitioned.

[0013] As a preferred embodiment of the cable erection and installation frame for communication engineering according to this utility model, the flexible strip is a high-strength nylon webbing.

[0014] As a preferred embodiment of the cable erection and installation bracket for communication engineering of this utility model, both the upper and lower ends of the vertical plate are fixedly connected to the mounting plates, and the outer walls of the two mounting plates are provided with multiple mounting holes.

[0015] The beneficial effects of this utility model are:

[0016] In use, the operator first passes multiple cables of different diameters through the space between the flexible belt and the support plate. Then, by rotating the manual drive mechanism, the screw rotates, causing the moving plate to move horizontally, thus tensioning the flexible belt. Guided and supported by multiple first and second guide rollers, the flexible belt moves smoothly through rolling friction. Relying on its own flexibility, it adapts to the diameter differences of the cables, applying pressure evenly to all cable surfaces, ultimately achieving simultaneous clamping in one go. This device eliminates the need for specialized clamps for different cable specifications, is easy to operate, and effectively solves the problems of poor flexibility and insufficient adaptability of traditional fixing methods.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0024] Please see Figure 1-4A cable installation frame for communication engineering includes a vertical plate 1. A support plate 2 for bearing the weight of the cable is fixedly connected to the right end of the vertical plate 1. Both the front and rear sides of the support plate 2 are bent downward to form a bending part 3. A fixing mechanism is provided on the support plate 2. The fixing mechanism is used to press and fix cables of different diameters onto the support plate 2.

[0025] The fixing mechanism includes a fixing plate 4 fixedly connected between two bending parts 3, a lead screw 5 rotatably connected between the two fixing plates 4, a moving plate 6 threadedly connected to the outer wall of the lead screw 5, a driving plate 7 fixedly connected to the upper end of the moving plate 6, a flexible belt 8 fixedly connected to the right end of the driving plate 7, and a plurality of grooves 10 with a triangular cross-section distributed horizontally on the upper end of the support plate 2. A first guide roller 11 is rotatably connected inside the plurality of grooves 10, and the flexible belt 8 passes around the plurality of first guide rollers 11 and is fixedly connected to the upper end of the support plate 2.

[0026] The fixing mechanism also includes a manual drive mechanism for driving the lead screw 5 to rotate.

[0027] In this embodiment: In the initial state, the flexible strip 8 is in a relaxed state. During installation, the construction personnel first pass the multiple cables to be laid, regardless of their diameter, through the position between the flexible strip 8 and the upper end of the support plate 2. Then, the upper end of the support plate 2 supports the cables. Since the support plate 2 has bending parts 3 on both the front and rear sides, the bending parts 3 can prevent the support plate 2 from bending downward under force, thereby improving the structural strength.

[0028] When it is necessary to fix the cable, the operator operates the manual drive mechanism to rotate the lead screw 5 between the two fixed plates 4. This, in turn, causes the moving plate 6 to move to the left, which in turn causes the drive plate 7 to move synchronously to the left. As the drive plate 7 moves to the left, it pulls the flexible belt 8. During this process, multiple first guide rollers 11 guide and support the flexible belt 8, gradually tightening it. The rotating arrangement of the first guide rollers 11 and the second guide rollers 9 effectively reduces the frictional resistance of the flexible belt 8 during movement.

[0029] When the flexible strip 8 is stretched, it presses down on all the cables placed on the support plate 2 from top to bottom. Because the flexible strip 8 itself is flexible, it can automatically adapt to the diameter differences of different cables and apply pressure evenly to each cable, finally pressing and fixing all the cables to the bearing surface of the support plate 2 at once.

[0030] In summary, this method allows cables of different diameters to be clamped and fixed onto the support plate 2 in one go, eliminating the need for special clamps to adapt to different specifications of cables. The operation is simple and effectively solves the problem of poor flexibility in existing technologies.

[0031] As a technical optimization of this utility model, the manual drive mechanism includes a drive frame 12 fixedly connected to the right end of the right fixed plate 4. A worm gear 13 is rotatably connected inside the drive frame 12. A worm wheel 14 is meshed with the outer wall of the worm gear 13. A transmission shaft is fixedly connected between the worm wheel 14 and the lead screw 5. A handwheel 15 is fixedly connected to the lower end of the worm gear 13.

[0032] In this embodiment: rotating the handwheel 15 drives the worm 13 to rotate, and the worm 13 drives the worm wheel 14 meshing with it to rotate. The worm wheel 14 transmits power to the lead screw 5 through the transmission shaft. Since the transmission pair of worm 13 and worm wheel 14 has a reverse self-locking characteristic, when the clamping action is completed, it can effectively prevent the reaction force of the cable from causing the lead screw 5 to reverse, thereby ensuring that the clamping force of the flexible belt 8 is stable and does not loosen.

[0033] As a technical optimization of this utility model, a through groove 17 is provided at the right end of the support plate 2. The inside of the through groove 17 and between the two bending parts 3 are respectively rotatably connected to the second guide rollers 9. The flexible belt 8 passes through the through groove 17 and around the two second guide rollers 9.

[0034] In this embodiment, the guiding action of the two second guide rollers 9 prevents the flexible belt 8 from contacting the support plate 2, thereby improving the smoothness of the transmission of the flexible belt 8.

[0035] As a technical optimization of this utility model, slide rails 18 are installed on opposite sides of the two bent portions 3, and the movable plate 6 is slidably connected to the two slide rails 18.

[0036] In this embodiment: Since the movable plate 6 is slidably connected to the two slide rails 18, the movement of the movable plate 6 is stable and without deviation.

[0037] As a technical optimization of this utility model, the corners of the support plate 2 and the two bent parts 3 on opposite sides are all smoothly transitioned.

[0038] In this embodiment: Since the corners of the support plate 2 and the two bends 3 on opposite sides are designed with smooth transitions, this structure can prevent the cable sheath from being directly scratched by the sharp right-angled edges during cable laying, thus preventing damage to the sheath.

[0039] As a technical optimization of this utility model, the flexible belt 8 is a high-strength nylon webbing.

[0040] In this embodiment, high-strength nylon webbing is used as the material of the flexible strip 8, which makes full use of the excellent properties of the material, such as high tensile strength, softness, wear resistance, corrosion resistance and aging resistance. This ensures that the flexible strip 8 has sufficient strength to compress the cable when tensioned, and its good flexibility can adapt to the diameter differences of different cables to achieve uniform compression.

[0041] As a technical optimization of this utility model, both the upper and lower ends of the vertical plate 1 are fixedly connected to mounting plates 16, and the outer walls of the two mounting plates 16 are provided with multiple mounting holes.

[0042] In this embodiment: the mounting plate 16 is fixedly connected to the upper and lower ends of the vertical plate 1, and the entire mounting frame can be firmly installed on the supporting structure such as utility pole, wall or cable tray using bolts and other fasteners through the multiple mounting holes of the mounting plate 16.

[0043] The working principle and usage process of this utility model are as follows: In the initial state, the flexible strip 8 is in a relaxed state. During installation, the construction personnel first pass the multiple cables to be laid, regardless of their diameter, through the position between the flexible strip 8 and the upper end of the support plate 2. Then, the upper end of the support plate 2 supports the cables. Since the support plate 2 has bending parts 3 on both the front and rear sides, the bending parts 3 can prevent the support plate 2 from bending downward under force, thereby improving the structural strength.

[0044] When the cable needs to be fixed, the operator operates the handwheel 15 to rotate the worm gear 13. The worm gear 13 drives the worm wheel 14, which meshes with it, to rotate. The rotation of the worm wheel 14 is transmitted to the lead screw 5 through the transmission shaft, causing the lead screw 5 to rotate between the two fixed plates 4. Since the moving plate 6 is connected to the lead screw 5 through its internal threads, and the moving plate 6 is constrained by the slide rails 18 on both sides, it can only move horizontally and cannot rotate. Therefore, the lead screw 5 drives the moving plate 6 to move to the left. The moving plate 6 drives the drive plate 7 to move to the left simultaneously. When the drive plate 7 moves to the left, it pulls the flexible belt 8. During this process, the flexible belt 8 is guided and supported by multiple first guide rollers 11, and the flexible belt 8 is prevented from contacting the support plate 2 by the guiding action of two second guide rollers 9, thus gradually tightening the flexible belt 8. The rotating arrangement of the first guide rollers 11 and the second guide rollers 9 effectively reduces the frictional resistance of the flexible belt 8 during movement.

[0045] When the flexible strip 8 is stretched, it presses down on all the cables placed on the support plate 2 from top to bottom. Because the flexible strip 8 itself is flexible, it can automatically adapt to the diameter differences of different cables and apply pressure evenly to each cable, finally pressing and fixing all the cables to the bearing surface of the support plate 2 at once.

[0046] In summary, this method allows cables of different diameters to be clamped and fixed onto the support plate 2 in one go, eliminating the need for special clamps to adapt to different specifications of cables. The operation is simple and effectively solves the problem of poor flexibility in existing technologies.

[0048] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
